Shed Permit in Charlotte, NC
Permit Summary
Do You Need a Shed Permit?
Exemptions
There is no general permit-free path for a permanent shed in Charlotte. A detached accessory structure that is 12 feet or less in all dimensions is exempt from the Mecklenburg County building permit, but it still requires a City Zoning Use Permit. A structure with any dimension over 12 feet requires the County building-permit path plus City LDIRL review.
Attached Shed Rules
Charlotte's published 12-foot permit split is specifically for detached accessory structures. The City's current permitting page separately lists an Addition among projects requiring concurrent Mecklenburg County building-permit and City LDIRL review; it does not publish a separate attached-shed exemption under the detached accessory-structure path.
Shed Use Rules
An accessory structure must support the principal structure or use and, for a single-family, duplex, triplex, or quadraplex lot, must be on the same lot. It may not be constructed before the principal structure or use receives its required approval, and it may not be used until required permits for the principal structure are passed and closed. A separate dwelling unit with its own cooking and sanitary facilities is regulated as an ADU rather than as an ordinary shed.
Zoning & Placement Rules
Zoning Rules
Charlotte UDO Article 17 requires a Zoning Use Permit for permanent accessory structures except permanent structures that require a building permit. Detached accessory structures over 12 feet in any dimension require a separate City LDIRL submittal alongside the Mecklenburg County building-permit process. Accessory structures must comply with the underlying zoning district and Article 17 standards.
Setback Rules
Accessory structures generally may not be placed in the established front or corner-side setback along a street or frontage, subject to listed UDO exceptions. An accessory structure in an established side or rear setback must be at least 3 feet from a lot line. If it is 24 feet or more in height, the rear setback is at least 15 feet and the side setback is the required side setback of the zoning district. In a residential zoning district, a detached accessory structure must be separated from the principal structure by at least 5 feet, with the UDO's limited breezeway exception.
Maximum Height Rules
Charlotte's general accessory-structure rules use 24 feet as a setback trigger rather than as a universal shed-height cap. The maximum permitted height depends on the underlying zoning district and any applicable overlay or site-specific standards; at 24 feet or more, the increased side and rear setbacks in Article 17 apply.
Lot Coverage Rules
For a lot in residential use, the cumulative square footage of accessory structures, excluding ADUs, may not exceed the heated floor area on the first floor of the principal structure. Accessory structures open to the sky do not count toward that Article 17 limit. City LDIRL zoning review also checks the applicable lot and coverage standards of the underlying zoning district.
Special Area Rules
Additional approvals can apply based on location. In a Charlotte Historic District Overlay, the owner must contact Historic District Commission staff and obtain a Certificate of Appropriateness when required before a building or other permit is issued; this review can apply even when no building permit is required. LDIRL review may also add Urban Forestry, stormwater/drainage, floodplain, erosion-control, and historic-district requirements; structures may not be placed in public storm easements.
Construction Requirements
Foundation Rules
For a shed that requires a County building permit, the foundation must comply with the currently effective North Carolina Residential Code and the approved permit documents. Mecklenburg County states that a footing must have the bottom of the concrete at least 12 inches below grade and must be inspected before concrete is placed; soft or inadequately compacted soil may require a deeper footing.
Fire Separation Rules
A shed subject to the North Carolina Residential Code must comply with the applicable R302.1 exterior-wall, opening, projection, and fire-separation rules. The code excepts walls of a dwelling and its accessory structures on the same lot from that exterior-wall separation requirement. Detached tool sheds, storage sheds, playhouses, and similar structures that are exempt from building permits do not require wall protection based solely on location on the lot, but projections may not extend over the lot line.
Permit & Review Path
Permit / Review Path
For a detached accessory structure 12 feet or less in all dimensions, apply to the City for a Zoning Use Permit through Accela Citizen Access; no Mecklenburg County building permit is required. If any dimension exceeds 12 feet, submit the Mecklenburg County building-permit application and a separate City LDIRL application, which the City says may be reviewed before or concurrently with County residential review. Mecklenburg County formal residential plan review applies to accessory buildings of more than one level and to projects using unconventional construction methods; other projects follow the applicable permit stream determined by the County.
Trade Permits & Professional Design
Trade Permit Rules
Mecklenburg County requires separate permits for building, electrical, heating/air-conditioning, and plumbing work when those scopes apply. Permanent electrical wiring, devices, or equipment added to or in an outbuilding require an electrical permit and inspection. Plumbing or mechanical systems added to a shed require the corresponding trade permit.
Professional Design Rules
Mecklenburg County states that residential plans generally do not require an architect or engineer seal. Structural elements that exceed the limits of the North Carolina Residential Code or otherwise do not conform to that code must be designed using accepted engineering practice and sealed by an architect or engineer; examples include engineered beams or trusses, unusual foundations, and unusual construction methods.
What You Need Before Applying
Requirements
A permanent shed must receive the applicable City zoning approval and comply with the Charlotte Unified Development Ordinance. A detached shed 12 feet or less in all dimensions uses the City Zoning Use Permit path. If any dimension exceeds 12 feet, obtain a Mecklenburg County building permit and a separate City LDIRL permit. Confirm the zoning district, proposed dimensions, setbacks, lot standards, drainage, tree, and any overlay constraints before submittal.
Required Documents
Typical submittal information includes the property address, project description and dimensions, and a plot/site plan showing the proposed shed and its relationship to property lines and existing structures. For County plan review when required, submit a complete electronic permit application and PDF plans, including associated trade contractors and project area information. City LDIRL review may also require urban forestry, stormwater/drainage, erosion-control, floodplain, or historic-district information depending on the site.
